Urdu JavaScript String Inspector

What the Urdu JavaScript String Inspector Does

The Urdu JavaScript String Inspector shows how a program really sees your Urdu text. It reports the length that JavaScript’s own count gives, the true number of characters, and the byte size, and it lays out every character in a table with its Unicode code point, its escape, and its byte count.

Urdu text often holds more than meets the eye: combining marks, joiners, and letters that sit outside the basic range. This inspector makes all of it visible, so you can see why a string behaves the way it does in your code.

Everything runs on your own device. Your text is never uploaded or stored, so it stays private while you work.

How to Inspect

1. Paste your text. Enter any Urdu text.
2. Read the counts. See the length, the code points, and the byte size.
3. Read the table. Look at each character with its Unicode value and escape.
4. Copy or download. Copy the report, or save it as a text file.

Length Versus Code Points

JavaScript counts a string in units of sixteen bits, which is what its length property reports. Most Urdu letters fit in one such unit, but some characters take two, and a combining mark counts as its own unit on top of the letter it sits on. The true number of characters, the code points, can therefore be smaller than the length. The inspector shows both, so you know which count your code is using.

The Escape Column

For each character the inspector shows the JavaScript escape, the backslash-u form you can paste straight into code. A character that takes two units shows both units, which is exactly how you would write it in a string. This makes it easy to put an exact Urdu character into source code without typing it directly.

Combining Marks and Joiners

Urdu uses combining marks for some vowel signs and invisible joiners to shape letters. These are real characters that a program counts, even though they may not look like separate letters on screen. The inspector flags them, so you can see where a string carries a mark or a joiner that affects its length, its comparison, or its display.

Who Uses This Inspector

Developers use it to debug string length. Testers use it to build edge cases. Students use it to learn Unicode.

Accuracy and Limits

The inspector reads the string with the same rules a JavaScript engine uses, so its counts and code points are exact. It reports the characters as they are given; a letter and a following combining mark are shown as the separate code points they are, which is how a program stores them, even when they display as one shape.

Good to know: to see the same text as JSON escapes, the JSON Unicode viewer shows that form.

Your Data Stays Private

The inspector runs fully in your browser with standard web technology. Your text is not uploaded or stored, and it is not sent to any analytics service. Only your star rating is sent, to record the tool’s rating. When you close the page, your text is gone.
